Overview
1. Why Do We Need To Change From Business As
Usual?
• Nature Can’t Satisfy Our Growing Demands
• Infrastructure Can’t Cope
• System Resilience in Seismic Regions
2. What Are The Solutions?
3. Examples In Practice

Water Stress Map

Problem 1:
More people concentrated in a small area.
There comes a point when nature cannot
meet the demands for water.

Infrastructure Can’t Cope

Infrastructure Can’t Cope
HUBER SE . www.huber.de
Water Losses from Urban Water Networks
Infrastructure Can’t Cope
HUBER SE . www.huber.de
Problem 2:
Central City infrastructure must work
harder as population densities increase.
Unfortunately this infrastructure is also
often the oldest.
Upgrading is expensive and disruptive in
the busiest part of town.
Upgrading water services costs twice: in
+ out.
Infrastructure Can’t Cope
HUBER SE . www.huber.de
• Expensive
• Disruptive
• Loss of business
• Noise/Dust Pollution
• Water infrastructure costs twice
(potable supply in + wastewater
out)

System Resilience in Seismic Regions
Source: CIESIN, Earth Institute at Columbia University
HUBER SE . www.huber.de
•Structures: Designed to
withstand seismic events
•Electricity: Standby generator
or multiple points of supply.
•Water: Storage tanks (8 – 24
hours supply)
•Wastewater: Typically nothing

System Resilience in Seismic Regions
HUBER SE . www.huber.de
Problem 3:
There are many cities located in seismically active
regions.
When earthquakes occur, waste water infrastructure
proves to be less resilient than other services, and
hence takes longer to recover.

The Problems Facing our Cities of Today
© Prof. Dr. Bischof
•More people = More resources needed. Increasingly
natural systems cannot meet this demand.
•Infrastructure in city centers is having to work harder.
Unfortunately in many cases it also tends to be old &
fragile and difficult/disruptive/expensive to upgrade.
•Conventional gravity waste water infrastructure is
relatively fragile in seismic events. Waste water is often
the weak link in re-establishing normal operations after an
earthquake.

The Cities of the Future
Rainwater
LESS Water brought in
LESS Wastewater removed
© Prof. Dr. Bischof
LESS Energy brought in
Reclaimed wastewater and rainwater for
amenity flow and groundwater recharge
Onsite wastewater treatment:
• reduces overall demand
• increases system resilience
Onsite or nearby energy recovery:
• reduces load on local energy supplies
